About the role of the JDBC Bridge connection mode for a long time, if the wrong place to hope that the great God can point out, thank you very much .... Be sure to point out that ...
Give me a jdbc little chestnut.
Step one: Establish a bridge-connected interface

void connection ();
Step Two: Create multiple classes (sim
Bridging Mode: separates object from specific behaviors and features so that they can change independently. Object is only an abstract concept. For example, "circle" and "Triangle" are under the abstract "shape", while "circle" and "Triangle draw" are under the "Drawing" Class of implementation behavior, then, "Drawing" is called by "shape ". "Shape" becomes an inheritance system, and "Drawing" becomes another inheritance system. The relationship betw
Intent/Definition: separates a set of implementations from the objects used by the other group so that they can change independently.
Problem: Multiple Derived classes of an abstract class must use multiple implementations, but class explosion is not allowed.
Solution: Define an interface for all implementations for use by all the derived classes of the abstract class.
Participants and collaborators: the concrete implementation of the abstract class uses the derived class of the implementation c

Bridge Mode: separates abstract parts from their implementations so that they can all change independently.
Explanation: the separation of abstract and its implementation does not mean that abstract classes are separated from their derived classes, but abstract classes and Their Derived classes are used to implement their own objects.

1: What is bridging?
In the bridging mode, the concept of bridging is not easy to understand. What is bridging? Why do we need bridging? How to bridge? After clarifying these problems, we can basically understand the meaning of bridging.
One by one, let's first look at what is bridging? The so-called bridge, in other words, is to build a

You can not underestimate this "primitive" combination, painting the blue sky with a large brush, painting small birds with a little brush, each with a special feature.Oh, you are not already looked out, good, I want to say today is bridge mode.

Instead of developing a dedicated network stack pattern on the web itself, XenServer uses existing network stack patterns for integration. There are two main types of XenServer network stacks: Bridge and Openvswitch mode. Bridge is a Linux-system technology, and Openvswitch is an open-source Virtual Switch software.

OverviewIn software systems, some types, due to their own logic, have a change of two or more dimensions, so how to deal with this "multidimensional change"? How can you use object-oriented technology to make this type easily change in multiple directions without introducing additional complexity? This is going to use bridge mode.

As far as the Java language system is concerned, the gof design mode is an implicit "bridge" between Java basic knowledge and J2EE framework knowledge ".
There are more and more developers who are familiar with Java, but there are not a few programmers who have been wandering at the language level. There are not many applications that really grasp inter
Bridges (bridge) mode
Bridge mode is a very useful model, but also a more complex one. Familiarity with this pattern is helpful in understanding object-oriented design principles, including the "open-close" principle (OCP) and the combination/aggregation reuse principle (CARP). Understanding these two principles will

In a software system, some types, because of their own logic, have two or more dimensions that change, so how do you deal with this "multidimensional change"? How can you use object-oriented technology to make this type easily change in multiple directions without introducing additional complexity?
Example 1: Imagine that if you want to draw a rectangle, circle, ellipse, square, we need at least 4 shape classes, but if the drawing needs to have a different color, such as

Bridge Mode Concept
The bridge mode is one of the constructor design patterns. Based on the minimum design prin
The purpose of bridging mode is to decouple the implementation of abstract and abstract methods so that they can be separated from each other.To control multiple machines through a common interface, you can use adapter mode to create an adapter class for each controller that can be converted to a call to an existing controller by speaking standard interface calls.
